Yeelight tunable white bulb M2

Hi, I have account 6360074475. I have 2 Yeelight tunable white bulb M2, but since I have added them as device, they just show as offline right after being added. I also not able to see them in my google home because of this.

I have tried to restart the process 3 times by switching off the bulbs 5 times and adding them again, but each time just showing as offline in yeelight app and google home. In Xiaomi home app it is not even recognized to be added.

Is the same to me. They are offline always, not connecting with app yeelight, not with mi home.
Do you have a solution yet?
